SPINNING-FRAME.

SPECIFICATION forming part of Letters Patent No. 380,563, dated April 3,1888.

Application filed me 1'1, 1887.

To aZZ whom, it may concern:

Be it known that we, RICHARD GILL, WIL- LIAM HY BUTLER, and SAMUEL SMITH, all of Lawrence, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Spinning-Frames, .ofwhich the following, taken in connection with the accompanying drawings, is a specification; and we do declare the following to be a full,'clear, and exact description of the invention, suffi cient to enable all to understand and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, all of which form a part of this specification.

Our invention relates to spinning yarns (either cotton or worsted, and for warp or filling) upon a spinning-frame similar in design, construction, and principle to the ringspinning frames, so called, in which the yarn is fed out from the fluted feed-rolls, and by them and their accompanying mechanism caused to pass to the bobbin upon the spindle, and there drawn and twisted as desired; and it consists of a hollow eyeleted whirl, within which revolves the bobbin, the latter being raised and lowered through a slotted sleeve carried by the builder-rail, and rotating with a spindle having a pin engaging the slot in the sleeve, the whole operating as herein described.

In the drawings, Figure 1 is a vertical section, the spindle and sleeve being in elevation; and Fig. 2 is a central vertical section of the entire device.

The same letters have been applied to similar parts in both figures.

The whirl '2 is supported upon and journaled within the stationary whirl-rail a, which carries eyelets o and p, through which the yarn to be spun is passed. Near its lower end the whirl a is provided with a groove, 8, in which runs a cord belt, 1, leading from a suitablydriven pulley, by means of which said wheel is rapidly rotated, and at its lower end the whirl a fits and rests in a step, at, carried in a stationary rail, 1), affording additional bearing and support therefor.

The stationary rail 6. carries a suitable step, Z, in which rests the lower end of a spindle, e, driven by a cord belt, q, passing around Serial No. 241,555. (No model.)

grooved pulley 7t, keyed to said spindle, which belt leads to a suitably-driven pulley. (Not shown.) This spindle extends vertically upward through step at and the center of whirl a to a point somewhatabove the upper eyelet, 0, on the latter. Fitting loosely on said spin-- dleeisasleeve,g, havingalongitudinalgroove, h, in one side engaging a pin, i, in the spindle, by which means said sleeve is caused to rotate with,but may be raised or lowered upon, the spindle, as will be readily understood. This sleeve 9 has a shoulder or face, j, at its lower end, which rests upon the builder-rail c, surrounding the spindle e, and forms a bearing and support for the sleeve. Loosely fitted over the upper end of the spindle, normally within the hollow whirl a, and resting upon and, supported by the upper end of the sleeve 9, is the bobbin f.

The builderrail 0 is connected with the builder motion by any suitable and wellknown mechanism. (Not shown, and forming no part of our invention.) This rail, however, by rising and falling raises and lowers the sleeveg, and with it the bobbinf, to properly shape the winding upon the latter, the spindle c and whirl n being meanwhile separately revolved by the independent belts shown.

The operation of our device will be readily understood by any person familiar with the art; but it may be described as follows, viz: In a ring-spinning frame the yarn passes from the feed-rolls above down through the loop on the ring, and from thence to the bobbin upon the spindle, and by the motion of the spindle the yarn flies around the ring in the loop, thereby drawing and twisting it in the usual manner. The ring-rail rises and falls by the operation of the builder mechanism, and by so doing properly winds the yarn upon the bobbin.

By our invention the yarn passes from the feed-rolls inthe ordinary way down through the eyelets p and o, and from thence to the bobbin f. Only the eyelets upon one side of whirl n are used at a time; but they are placed on each side for convenience in threading and also to balance the whirl in revolving. The eyeleted whirl a revolves independently of the spindle e and at a different speed, and by so doing regulates the drawing and tension of the yarn as well as the twist of the same. The rail a being stationary, the shaping of the winding of the yarnupon the bobbin f is accomplished by the rail 0 being operated by the builder motion, and in so doing raises and lowers the sleeve g, which holds the bobbin upon the spindle e, and in this way is the winding of the yarn upon the bobbin accomplished, instead of the upper rail being raised and lowered by the builder-motion, as in an ordinary ring-spinning frame.

Now, what we claim as new, and desire to secure by Letters Patent, is

1. The hollow whirl n, having eyelets o and p, and means for rotating said whirl, in combination with the spindle 0, extending loosely through the vertical center of said whirl, means for rotating said spindle independently of the whirl, the pin 2' on said spindle, and the sleeve 7 g, fitting loosely on the spindle, and provided with the slot h, engaging said pin 2, substan-r tially as described.

2. The hollow whirl 12, having eyelets o and p, and means for rotating said whirl, in combination with the spindle 6, extending loosely through the vertical center of said whirl, means for rotating said spindle independently of the whirl, the pin 6 on said spindle, the sleeve g, fitting loosely on the spindle, and provided with the sloth, engaging said pin 2', and the builder-rail a, substantially as described.

In testimony whereof we have signed our names to this specification, in the presenceof two subscribing witnesses, on this 11th day of June, A. D. 1887.
